What this breaker carries
The Siemens 3VA2010-5HL36-0KF0 is a 3-pole IEC molded-case circuit breaker on the 3VA2 frame, rated for line protection with an ETU320 electronic trip unit (LI characteristic — long-time and instantaneous). Breaking capacity lands at Icu = 55 kA at 415 V AC, which puts it in breaking capacity class M — enough for most industrial secondary-distribution panels where the available fault current sits in that range. The continuous current rating In is 100 A, with overload protection (Ir) adjustable from 40 A to 100 A and short-circuit protection (Ii) adjustable from 1.5 to 12 times In. That means one breaker covers a wide band of feeder or branch-circuit sizes without swapping the frame.
Integrated accessories
Factory-fitted with a shunt trip (STL) rated for 220–250 V DC or 208–277 V AC, plus one auxiliary switch HQ and one trip alarm switch HQ. That covers remote tripping and status feedback without adding separate modules. Termination is clamp (box lug) type — no special crimp tooling needed for the panel builder, and it accepts a solid or stranded conductor range typical for 100 A feeders.
